Abstract

The characteristics of the batwing radiator, which is the heart of the superturnstile antenna system for VHF-TV broadcasting, are broad bandwidth. We investigate the modified batwing antenna for UHF used for digital terrestrial broadcasting. The characteristics of the 2-element modified batwing antenna with an infinite reflector and with a wire screen for the finite reflector are calculated by NEC-Win Pro. These antennas are connected with each element by a parallel feed line and fed at the center of this line. We estimate these antennas from 470 MHz to 770 MHz of the UHF-TV broadcasting band in Japan. The broad-band properties and the power gain of about 11 dBi are obtained in these frequencies.

数字地面广播天线的特性

蝙蝠翼辐射体是超高频电视广播超级旋转门天线系统的核心，其特点是宽带宽。研究了用于数字地面广播的超高频改进蝙蝠翼天线。利用NEC-Win Pro软件计算了具有无限反射面和有限反射面带有钢丝屏的2元改进蝙蝠翼天线的特性。这些天线通过一条平行馈线与每个元件相连，并在这条线的中心馈电。我们估计这些天线在日本的超高频电视广播频段的470兆赫到770兆赫之间。在这些频率上获得了宽带特性和约11 dBi的功率增益。
